Alright I'm new to X-Wing so I need as much feedback (good/constructive) as I can get with the following list:

Echo w/ ACD - 34 pts

Delta Squadron Pilot w/ Ion Cannon - 33 pts

Delta Squadron Pilot w/ Ion Cannon - 33 pts

Total List - 100 pts

Basically what I'm thinking is to use the Defenders to screen and lock enemy ships up with their Ion Cannons then K-Turn behind all while Echo maneuvers and cloaks his way in

I like the idea but this list will most likely suffer to turret and high pilot skilled builds. I'd remove one of the defenders and add a shuttle or a bounty hunter. It'll give your list some hit points and now you have a big target to keep some of the focus off of your phantom and your defender might be able to get behind them. I'd try this:

Echo with Veteren Instincts, advanced cloaking device, intellegence agent. (36)
Onyx Squadron Pilot with ion cannon (35)

Omicron pilot with intelligence agent, engine upgrade, and advanced sensors (29)

vi on echo gives you a better ps on other ships, onyx can avoid predator, and your shuttle and echo can predict where your opponents are moving so you can keep onyx behind them better and know who's gonna k-turn to face onyx.
